This was the least expensive chair mat and also the only good size for my desk area. It works fine but almost immediately the weight of the occupied chair created dents in the plastic which the chair rolls into. A minor annoyance and much less inconvenient than using an office chair on carpeting or spending more money. Overall good value for the money.
I use this for my home office. It serves the purpose adequetly I guess. But the plastic deteriorates withing a year. With low pile carpeting it's going to do that. They have one for more money. I figured just buy a new one every year. Nothing last forever.
